Introduction
Creating an Islamic will in New South Wales requires a careful balance between religious obligations and Australian legal requirements. A significant challenge in this process is the risk of partial intestacy, where a will fails to dispose of the entire estate. In such cases, the remaining assets are distributed according to the secular rules of the Succession Act 2006 (NSW), potentially overriding the specific inheritance instructions mandated by Islamic principles.
This issue often arises because the fixed inheritance shares stipulated in the Qur’an may not account for all of a person’s assets under NSW law, creating a legal vacuum. This guide explains how to navigate this conflict by providing strategies for drafting a comprehensive Islamic will. Proper planning ensures your estate is distributed according to your faith while remaining fully compliant when navigating Australian succession law, thereby avoiding the unintended consequences of partial intestacy.

Islamic Will Partial Intestacy Risk Checker
Quickly check if your Islamic will in NSW risks partial intestacy and unintended asset distribution under Australian law.
Does your current or planned will specify how ALL assets, including any residue, should be distributed?
Does your will attempt to distribute assets strictly according to fixed Islamic inheritance shares (Mawarith schedule)?
Have you reviewed your will with a solicitor experienced in both Australian succession law and Islamic inheritance?
✅ Your Will Minimises Partial Intestacy Risk
Great work! Your will appears to cover all assets, including the residue, and has been reviewed by a solicitor with expertise in both Australian succession law and Islamic inheritance. This significantly reduces the risk of partial intestacy and ensures your estate is distributed according to your wishes and faith.
For ongoing peace of mind, review your will after major life events or asset changes.
Relevant Law: Section 32 of the Succession Act 2006 (NSW)
⚠️ Your Will May Risk Partial Intestacy
Warning: If your will does not address every asset or the residue, or if you are unsure, there is a real risk that part of your estate could be distributed under the intestacy rules in the Succession Act 2006 (NSW). This may override your religious wishes and result in unintended beneficiaries.
It is crucial to include a valid residuary clause and seek legal advice to ensure full compliance.
Relevant Law: Section 35 of the Succession Act 2006 (NSW)
❌ High Risk: Your Will Likely Causes Partial Intestacy
Critical issue: Your will distributes assets using fixed Sharia fractions but does not specify what happens to any residue, and it has not been reviewed by a qualified solicitor. This almost certainly creates a partial intestacy, meaning the undistributed portion will be allocated under the Succession Act 2006 (NSW), not Islamic law.
Immediate legal review is strongly recommended to protect your religious and family interests.

How Partial Intestacy Specifically Affects Islamic Wills
The Fixed Shares of Islamic Inheritance Principles
An Islamic Will distributes an estate according to the Mawarith schedule, a key part of understanding Islamic inheritance that outlines the fixed shares for beneficiaries as stipulated in the Qur’an. Consequently, this system implements a form of forced succession, which is characterised by the following principles:
- Beneficiaries and their specific percentages are predetermined by Shari’ah.
- The framework is based on the belief that God's will should take precedence over human desires, unlike a standard Australian will where the individual has broad discretion.
- It ensures the security and preservation of the extended family unit through a system of fixed shares determined by the beneficiary's relationship to the deceased.
When Sharia Fractions Create a Residue
The application of fixed Sharia fractions can sometimes result in a portion of the estate not being fully distributed. Furthermore, the specific shares allocated to each beneficiary depend on which family members survive the deceased, making the final distribution of assets difficult to predict with certainty.
A residue is generally created during the distribution process when:
- The designated Qur’anic heirs do not exist.
- The distribution of their fixed shares results in a leftover sum.
Under Islamic inheritance principles, this residue is typically allocated to the deceased’s male agnatic heirs.
However, if an Islamic will drafted for use in Australia does not explicitly state how to distribute this residue, it can directly lead to a partial intestacy under NSW law.

The Critical Difference Between Residue in Sharia & NSW Law
How Islamic Inheritance Distributes the Residue
Under Islamic inheritance principles, the distribution of an estate follows a specific order.
The primary beneficiaries are the Qur’anic Heirs (also called “Sharers”), who receive fixed portions of the estate:
- Spouse
- Parents
- Daughters
If the Qur’anic Heirs do not exist—or if, after their portions are allocated, part of the estate remains—that leftover amount becomes the residue.
The residue is inherited by a class of heirs known as Residuaries:
- Sons
- Brothers
- Paternal uncles
- Nephews
How the NSW Succession Act 2006 Distributes the Residue
Australian succession law treats the residue very differently. If a will distributes some assets but overlooks the rest, the gap is called partial intestacy. Because the will gives no directions for the remaining portion, that remaining portion lacks any testamentary instructions.
In such cases, the residue is not distributed according to Islamic principles. Instead, distribution follows the statutory rules in the Succession Act 2006 (NSW).
When partial intestacy arises, the deceased’s wishes are absent for that amount, and the law applies a predetermined formula to decide who inherits.

Consequences of Partial Intestacy for Australian Muslims
Unintended Beneficiaries & Disappointed Heirs
When an Islamic will results in partial intestacy, the undistributed residue of the estate is governed by the Succession Act 2006 (NSW). Consequently, this legislation outlines a specific hierarchy for distributing assets, which often conflicts with Islamic inheritance principles.
Under NSW law, the rules of intestacy prioritise certain family members in a set order:
- The spouse or de facto partner is typically first in line to inherit the entire estate.
- If there is no surviving spouse, the deceased's children will inherit the estate in equal shares.
- Only when there is no spouse or children do other relatives, such as parents or siblings, become entitled to the estate.
Ultimately, this legal framework can lead to unintended outcomes for Muslims planning their estate according to Sharia. Specifically, the residue is handled in ways that contradict these plans:
- Under Islamic principles, it would typically be allocated to male relatives like sons or brothers.
- Instead, it is diverted to the beneficiaries prioritised by the Succession Act 2006 (NSW).
- This diversion overrides the testator's religious wishes, which can leave the intended Islamic heirs disappointed.
The Risk of Contravening Religious Duties
For many Muslims, the distribution of an estate is not merely a financial matter but a significant religious obligation. Furthermore, Islamic inheritance law is considered a divine mandate, meaning that ensuring one's assets are distributed according to Sharia is seen as a fundamental duty.
A partial intestacy that triggers the application of Australian secular law results in a distribution that is non-compliant with these religious principles. This creates significant legal and spiritual risks:
- If a family member disputes an informal arrangement to follow Sharia, an Australian court will strictly enforce the distribution set out in the Succession Act 2006 (NSW).
- This enforced distribution can result in a failure to fulfil religious duties, as the estate would not be managed in accordance with the Islamic faith.

Strategies to Avoid Partial Intestacy in Your Islamic Will
The Importance of a Valid Residuary Clause
Partial intestacy can be avoided by preparing a thoroughly drafted will that accounts for every aspect of your estate. A key strategy in estate planning is to include a valid residuary clause, which specifies how any remaining assets should be distributed after all specific gifts and debts have been settled.
Ensuring all parts of your estate are covered is crucial, especially when acquiring new assets or selling existing ones. By explicitly directing the distribution of the residue, you can achieve the following:
- Prevent any portion of your estate from being left without instructions.
- Avoid triggering the application of intestacy rules under the Succession Act 2006 (NSW).
Seeking Professional Legal & Religious Advice
It is vital to understand if Islamic wills are legally valid in Australia. A will that simply states your estate should be distributed according to Sharia may be considered too uncertain for an Australian court to enforce.
Furthermore, the distribution of assets under Islamic inheritance principles can be complex and difficult to predict, as the shares depend on which family members survive you. For these reasons, seeking guidance from an experienced solicitor is highly recommended, particularly if your circumstances are complex.
A legal professional with expertise in both Australian succession law and Islamic inheritance can help you prepare a valid will that achieves the following:
- Remains compliant with all legal requirements.
- Ensures the document accurately reflects your wishes.
- Successfully avoids the risk of partial intestacy.

Conclusion
Planning an Islamic will in NSW requires careful attention to how Sharia principles interact with Australian law to avoid partial intestacy. Failing to account for the entire estate, particularly the residue left after fixed shares are distributed, can result in assets being allocated under the Succession Act 2006 (NSW) instead of according to your faith.

Frequently Asked Questions
If a Muslim dies in NSW without a will, their entire estate is distributed according to the intestacy rules outlined in the Succession Act 2006 (NSW). This means the assets are allocated based on a legal hierarchy of relatives, not according to Islamic inheritance principles.
Yes, an Islamic will can be recognised under Australian law as long as it meets the formal legal requirements for a valid will in NSW. It functions much like a standard Australian will by distributing the estate in specific percentages to designated beneficiaries.
A daughter may receive a smaller share than a son because of the "half rule" in Islamic inheritance, which allocates a male heir a portion equal to that of two female heirs. This principle is based on the traditional social expectation that men are financially responsible for their female relatives.
If your will distributes only a specific share of your property and fails to account for the entire estate, the remaining portion is subject to the laws of intestacy. This scenario is known as a partial intestacy, and the undistributed assets are allocated according to the Succession Act 2006 (NSW).
A non-Muslim cannot inherit from the fixed Sharia portions of an estate, as these are designated for Muslim heirs only. However, a non-Muslim can receive a gift from the one-third of the estate that the will-maker is permitted to bequeath at their own discretion.
To avoid partial intestacy, it is essential to have a thoroughly drafted will that accounts for your entire estate, including a valid residuary clause to direct any leftover assets. You should also review and update your will regularly, particularly after significant life events or changes in your assets.
Yes, eligible persons, including children, can challenge an Islamic will in an Australian court by making a family provision claim. This can occur if they believe the will fails to make adequate provision for their proper maintenance and support, judged against prevailing community
Yes, a will must be in writing to be legally valid in NSW and must also be signed and witnessed in accordance with the Succession Act 2006 (NSW). Although Islamic law can recognise oral wills, the stricter formal requirements of Australian law must be satisfied for the will to be enforceable.
The 1/3 bequest option in an Islamic will, also known as Wasiyyah, allows the will-maker to freely give up to one-third of their estate to individuals or organisations that are not prescribed heirs under the fixed inheritance rules. These discretionary gifts can be made to non-relatives, non-Muslims, or charities.
